Hello all - me again. Just wanted to update on this. I have a third battery, made a plywood (3/4") extension shelf so I can fit all three batteries in between the trailer tongue rails. I tried to run my microwave off of the 1500 watt inverter that I had and it barely runs it, plus the inverter goes into alarm while it's running.
For now, I will just enjoy the extra time between needing to run the gen with the bigger battery bank and run the gen when I need to make popcorn in the microwave. I am also adding a third 100W solar panel.
As for the wiring for the battery bank in parallel, I want to do it with the largest gauge wire that is reasonable. From my research I have found that 4/0 is the biggest that's normally used, I already own a hydraulic lug crimper so should I just go for the big 4/0 and be done with it? Or is the 4/0 complete overkill for interconnecting the batteries? What would you recommend?
I am attempting to future-proof myself, because I know I will be adding a beefy inverter in the future. I will connect to the TT 12V system using 2 gauge wire (I have some left over from another project), no need for it to be crazy big when the TT uses 6 gauge. Of course, the inverter will be wired with 4/0 when the time comes.
Thanks for the advice!
Scott P
